' WATER GAUGE.

This invention relates to water gauges and the object of the same is the provision of means for eliminating the breaking of water glasses in any locomotive, or other steam boilers.

stationary It is to be understood that a water glass wears away from the top or end,

caused by continual cutting of lime, mud, and water treating ingredients, and causes a glass to burst, so in using our devices in combinatlon, one in the top and one in the bottom of a glass, last to five years,

it will make a glass from four because there will be no wear other causes.

With the foregolng and other v1ew, our invention obj ects in comprises certain combinations, constructions and arrangements of parts panying fication, in the appended claim. In the drawings:

drawings, described in as will be illustrated in the accomthe speciand more particularly pointed out Figure 1 is a view partly in elevation and partly in section of a water ing our invention.

gauge embody- Figure 2 is a perspective View of a copper or other metal protecting device that we have perfected, used in combination with the other parts of a water gauge.

Referring to the drawings by 1 designates the boiler, to which gauge is attached. This water cludes a glass tube 2, copper numerals, the water gauge inor other metal protecting devices 3, one at each end, two rings 4 (one at each end) laid against the thin outer flange 5 of the protecting with caps 6 screwed upon the rmgs 4i,

devices as shown in Figure 1. Within each cap 6 1s a rubber gasket 7, which clamps against the lnner face of flange 5, as well as against the upper end of the glass tube 2, thereby sealing the end against any possibility of water leaking through to the cap 6.

Suitable connecting means 8 is formed upon the rlng 4 for connecting the device to boiler 1. The protecting devlces 3 include a thin cylindrical body 9 which tight against the inner wall of its preferably glass tube 2 and a considerable distance therein, with the'end covered by outer flange 5 formed on the body 8. This device 3 covers the outer end of tube 2, as well as preventing water from coming in contact with the tube 2 a considerable distance from the end thereof. This device 8 practically seals the a outer ends of the glass tube 2, which prevents the continual cutting of lime, mud, and water treating ingredients on said glgass tube, thereby increasing the life of the tu e.

It is to be noted that as each ring 4 is screwed more tightly into its respective cap 6, the rubber gasket 7 will be crowded more forcefully against the flange 5, whereby it will be impossible for any water to pass between ring i-and flange 5, or between tube 2 and gasket 7, to the cap 6.

o have produced a very efficient structure with reference to both the thin protecting devices and the water gauge as 7 a whole, resulting in meritorious advantages as hereinbefore mentioned.

The protecting device 3 at the top of the tube 2 has a relatively long 'cylindrical body 9 with arelatively narrow flanged end 5, for fitting snugly and efiiciently in the complete device, as clearly shown in Figure- 1, the device 3 at the bottom has a relatively short body 9 so that the glass can be read all the way down to the lower cap 6.

While we have described the preferred embodiment of our invention, and have illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to'which this invention relates, during the extensive manufacture of the same, and, we, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claim.

What we claim is:

In a device of the class described, the combination ofa glass tube,'copper protecting devices in the ends of said glass tube, each protecting device comprising a comparatively long cylindrical body fitting tightly against the inner face of the glass said flange and adapted to be held tightly 10 against the outer face of said flange and clamping the gasket tightly against the glass tube and the inner face of the flange, substantially as shoWn and described.

In testimony whereof We hereunto affix 15 our signatures.
